IMPROVEMENT IN LAMPS.

S pecilication forming part of Letters Patent No.. 138,185, dated April 22, 1873; application filed f November 27, 1872.

To all whom 'it may concern:

Be it known that I, JULIUS A. PEASE, of Boston, State of Massachusetts, have made certain Improvements in Lamps, of which the following is a specification:

This invention relates to that class of lampsl used in burning Solid or semisolid oils or fats, such as parafine, adamantine, tallow, or any similar fatty substance that requires to be melted before use; and it consists in providing al cup adjustably suspended above the flame or chimney, and communicating by means of afeed-tube with a shallow basin surrounding the wick-tube, said basin having outlets or overiiow openings, so that if the oil is fed down faster than it is consumed the surplus oil will run into a drip-cup or reservoir contained within the pedestal of the lamp, arranged to receive and retain the overliow or Waste fats.

In the drawing referred to in this Specification and' making a part of the same, the ligure represents a vertical section of a lamp embodying my invention.

B represents the base or pedestal of the lamp, having within it the dripAcup A, the drip-cup being held in place by springs L attached to the inner surface of the shell forming the base of the lamp. This drip-cup is represented as a pan having a central depression, but may be of any shape that will conform to the base of the lamp, and may be secured by a screw-thread, or in any other wellknown manner. C is a shallow basin, similar in general outline to drip-cup A, and is placed at the point usually occupied by the lampbowl. Near the upper edge of basin C are overliow-openings c, to allow the escape of any melted matter that may accumulate more than is required to ll the basin and feed the light. d d are openings to supply air to the burner. The wick-tube E passes centrally through this basin, and is soldered tight, being perforated above the basin at points e, to allow the melted matter to saturate the wick. The wick-tube is slotted, as usual, and provided with a ratchet, I, to raise and lower the wick. D is a spreader,fof any ordinary construction. Fis a cup or reservoir for the fatty matter, provided with a Suitable cover and secured at the proper distance above the lampiiame by means of standard G and slide K. From reservoir F a feeding-tube, H, passes through the spreader into basin C for the delivery of the melted fats.

If the hole in this feeding-tube is properly gaged it will feed the oil only just so fast as the light will consume it.

The reservoir F having been lilled with tallow, paraffine, or other suitable material, a little oil is poured into the basin around the Wick tube, saturating the wick, which is then lighted. The oil in the basin supplies the wick until the matter in reservoir F begins to melt and feed down through tube H.

This is only necessary in starting the -iirst time, as afterward there is always some material remaining in the Wick-tube basin after the light is put out which will suflice for starting the light thereafter, provided the Wick is wet with a little alcohol or turpentine.

It Will be seen that in a lamp constructed -as above described, the solid or semi-solid fats may be burned giving a light equal to the best kerosene, and Without danger; and it is also evident that the light will rather increase than otherwise, as the lamp burns and becomes warmer, and the oil more limpid.

Having thus described my invention, I

claiml. The combination of the Wick-tube basin, the pedestal, and the drip-basin, substantially as and for the purpose specified.

2. The adjustable reservoir, provided With the feeding-tube, in combination with the Wicktube basin, and drip-basin within the pedestal, as and for the purpose set forth.
